HTA+Batch hybrid; sheet.cssRules.length fails when file is too large

Posted: 14 Apr 2019 17:37

After reading about HTA input forms on viewtopic.php?t=6581, I immediately tried to work it into a script I was creating. However, after the script grew larger and larger, it suddenly started failing. In one part of the Javascript in the HTML section, I have this function:

Code: Select all

function insertRule(rule){
  sheet.insertRule(rule, sheet.cssRules.length);
 }
To insert CSS rules. However at some point, it kept displaying:

Code: Select all

"Unable to get propery .length of undefined or null reference"
After some experimentation, I discovered that it was because of the file size. For example:

Code: Select all

Works fine. However, add a couple more lines:

And suddenly, it doesn't work. Are there any ways to fix this and overcome this problem?

I suspect that either the html comment has a maximum length, or the "<hta:...>" element must be within a given offset of the file, else some weird bug triggers... . I suggest to use a comment as short as possible and put the batch portion into a script tag.

So hopefully the folllowing works (without triggering bugs):

Code: Select all

<!-- :: Batch section
goto :main
-->

Sidenote: In addition it is recommended to define functions, before using them - although it seems to work here (and also isn't the cause of the above bug).

Edit: Added the ":main" label... .

Put it in it's own <SCRIPT> tag and it works. Thanks!
